Let’s say that, for the sake of example, there is a 37 next to "Paid Spot (CPM). In the Injector Manager screen.  And a 12 next to Unpaid Spots.  Does that mean that the station has have 37 clients inserting ads or 37 clients including the Ad Wire spots?

Actually, no.  That means that there are 37 individual spots in the station’s inventory that are classified as Paid Spot (CPM) and 12 items that are categorized as Unpaid Spots.  Each category of available content (that is to say, categories that are selected as playable in the station template) are listed in the Inventory Helper on the left side of the Injector manger inventory screen.  If there are items in inventory for that category, then the number of items assigned to each category are listed there as well.

We always recommend that each category listed have at least 15 items in inventory.  Also, remember that in order for these items to be playable, that category MUST be selected and checked in the station Template.
